CONDENSER FOR CARDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 320,778, iated Jane 23, 1885.

Application filed April 1o, 1883. (No monti To all whom t may concern:

Be it known that I, WEBSTER GrLr., a eiti zen of the United States, residing at the city of Camden, in the county of Camden and State of New Jersey, have invented certain new and useful improvements in Gondensers for Carding-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification, in which- Figure l is a plan, partly in section and partly broken away, of a condenser exhibiting my improvements. Fig. 2 is a side elevation of the same. Fig. 3 is an elevation of side opposite to that shown in lastnamed gure, partly broken away and partly in section. Fig. l is an end elevation of the condenser. Fig. 5 is a perspective view of one of the gearing-boxes. Fig. 6 is a side view of one of the rolls with its adjustable bearing. Fig. 7 is an under side View of the adjustable bearing devices. Fig. 8 is an end view of the rolls and apron. Fig. 9 is a perspective view of one of the eccentrics.

.My invention has relation to the condensing mechanism of woolcarding engines; and it consists in the novel means for supporting the gearing through which the rubbing-rolls are rotated, while they are at the same time given a reciprocating movement on their axes from eccentrics, hereinafter described.

Heretofore in woolcondensers the rolls of which have been geared together and a longitudinal reciprocating motion obtained the gearing has been arranged to remain in one position-that is, it has had no lateral movement-while the rolls played or moved lengthwise, the connecting shafting between the gearing and the rolls being so formed as to accommodate itself to the changes in relative positions of the rolls to the gearing.

My invention differs from such condensers in the provision of sliding boxes to contain the gearing, the entire train of which for each set of rolls is contained within a box, to which reciprocating lateral motion is imparted from an eccentric on a vertical shaft. Under such an arrangement the gearing and rolls move laterally together. The rotary motion of the rolls is obtained through the gearing from shafts on which the gearing-boxes slide and on which are mounted the first wheels of the trains of gearing.

Referring tothe accompanying drawings, A designates that portion of the frame of a condenser which sust-ains the gearing and other devices pertaining to the rolls, as hereinafter mentioned.

B B designate the upper and lower sets of rolls, respectively, of a train arranged in the usual alternating order, with, say, four rolls above and five below. A supplementary roll, B2, is added to the upper set when the apron is to be used, and this roll is supported by an adjustable box, D, constructed and arranged, as hereinafterfully described, so that it may be raised or lowered in the are of a circle to adjust the apron relatively to the rolls below, and which may bealso adjusted to take up the slack of the apron.

c @designate the shafts of the four top rolls,

which have lugs or pins, o, which fit in bay-` onetsslots o in the hubs of the gears d. To fix the shafts in the hubs they are merely in serted therein and given a short turn or partial rotation, and they are withdrawn when required by a reverse motion. These gear wheels engage in the usual manner with the intermediate wheels orpinions, d3, and with the latter make up the entire train for a set of four rolls.

The entire train of gearing is contained in a box,C/. Beveled grooves c,Fig. 5, are formed in the lower corners of the box,and the shouldered portions c2 of such grooves rest on beveled cleats c, as shown in Fig. 3, which are adjustable by means of bolts e, Figs. 3 and 4, upon the bars c, and form slides upon which the box plays, and which may be adjusted to fit nicely and avoid irregular motion, as well as to take up wear. halves, being divided horizontally at its middle into two sections, which are bolted together by bolts k', and separable to give access to the gearing. The gearing does not require special or lengthy description, as it is not distinctively peculiar. As is usual in geared condensing-rolls, the gearing is graduated so as to produce gradnallyincreasing speed of the rolls, the effect ofthe increase in thespeed being to make the rolls driven by such gear- Thelower box is made in I ingv drawing-rolls. Itislusual to provide that the top rolls shall yield slightly upward to adapt the train to the varying conditions of the slubbing. It is also desirable to provide means for adjusting the rolls and gearing laterally. To this end-the side walls of the upper gearing-box, C, are made with shaft-openings c5 c5, Fig. 5. Theidlers or intermediate wheels, d d, of the train are supported in the solid portions of the walls between these openings and said solid portions, and are connected at the top by cross-pieces or bridges cG c6.

Pillow blocks or bearings E E fit over the openings in the sides of the gearing-box C', said pillow-blocks consisting each of an approximately U-snapedV bracket having two vertical sides, e e', and a cross-piece, e2. The sides e e afford bearings for the hubs of the gear-wheels-d, which receive one end of the shafts of' the upper rolls,B, and said sides are such distance apart that they will strad dle the sides of the gearing-box C', or will stand, when fitted in place, just outside of the eX- terior plane of the sides of said gearing-box. Hence the pillow-blocks E may be moved on the gearing-box in the direction of the length of the latter, and toward either end thereo.

Inside of each of the pillow-blocks is an adjusting-bracket, F, which is also of approximately U shape, and held in place by a central screw, f, which passes through a slot, e3, in the cross-bar e2 of the pillow-block and enters a threaded opening` in the cross-barf of the adjusting-bracket F. The sides or legs of the ad j Listing-bracket are less distant apart than are the sides of the gearing-box, and are of greater width than the shaft-openings c5 in saidlatter sides. Hence, when the pillowblocks are applied to the gearing-box the sides of the former embrace or stand outside of the openings in the sides of the latter, while the legs ofthe adjusting-brackets stand inside the gearing-box, the openings in the sides of the latter thus coming between or being embraced by the depending sides or legs of the pillowblocks and the adjusting -brackets, respectively.

rThe shafts of the upper rolls have bearings for one of their ends in the hubs of the gears d', their opposite ends being supported in bearings d2 on the housing or frame A. Said shafts pass through the openings c5 in the sides of the gearing-box, which latter are of sufficient width to permit lateral play or movement of said shafts therein when req'iired.

For adjusting purposes the center screws, f,

. holding the pillow-blocks and adj usting-brackets together, are first loosened and said pillowblocks then moved along on the adjustingbrackets in either direction of the length of the gearing-box C. Said screws f are then made fast. The adj listing-brackets cannot be moved laterally while in the gearing-box, as they fit snugly in vertical Ways c7 c", Fig. 5, in said box C.

The pillow-blocks are also provided each so as to lift its rolls, the end screws, e4 et, are

turned down, while to lower said block the screws are turned upwardly or outwardly. The movement of thepillow-block adjusts the roll whose shaft has a bearing in the hub of the gear-wheel supported in said block. The weight of the pillow-block and the roll will keep said block down in its proper place and maintain its gear-wheels in mesh with the idlers with which they engage, and said block will yield upwardly to accommodate its roll to lumps, &c., in the slubbing, Y

Gl designates the eccentricshaft through which the rolls are reciprocatedon their axes, and G2 G2 are the eccentric straps or yokes coupled to the boxes C CZ by means of the arms h 71J projecting forward from the bottoms of the boxes, as shown, and provided with anti-friction rollers, upon which play the slotted arms g g of the eccentric straps G2.

For imparting motion to the eccentric straps, there is provided for each strap an eccentric, I, mounted on a shaft, G', to which power is applied from any suitable source. As the shaft rotates the eccentric gives to the eccentric strap or yoke G2 an oscillating or orbital motion, and this is converted into a rectilinearly-reciprocating movement ofthe gearing-box and its contents'.

An apron, H, is provided for a portion of the upper rolls and rubs on the rolls below it. Means are provided, as hereinafter described, for regulating the tension of the apron and for adjusting it relatively to the rolls beneath.

l? designates the driving-shaft for communicating motion to the gearing in box C. Said shaft carries conical anti friction rollers p, which are adapted to the double dovetailed channel p in the hub p3 of the first gear-wheel of the train: A similar construction is provided for the lower box, C2.

The channeled hubs, anti-friction rollers, and shafts constructed as described constitute couplings for each box and the gearing therein, whereby rotary motion is communicated to said gearing, while, at the same time, said boxes are permitted lateral reciprocating movement on said shafts.

The roll B2, for adjusting the apron H, has its journals supported in boxes D, which forni the outer terminals of swivel-arms D'l D2, whose inner ends have bosses i, with openings to receive, respectively, the hub of the roll 4 and a hub or boss on a bracket, K, mounted on the housing or frame A. Said arms may be moved in the arc of a circle, carrying the roll which they support, to raise or lower the same.

To hold the arms and roll in any adjusted position, there is provided a bolt or set-screw, m, which passes through a segmental slot, a, in the gearing-box O, and enters an opening in the arm D2.

To take up slack or regulate the tension of 'the apron, the swivel-arms D2 D2 are each IOO IIO

made in two sections, d" d", extensible upon one another, and held by a set-screw, s, passing through a slot in one of said sections and into an opening in the other.

To facilitate making adjustment of these sections, the set-screw s passes through the eye t of the draw-bolt T, which latter fits in the slot u in an arm, U, on the box D, and is provided with adj Listing-nuts u a.

The advantages of the construction herein shown and described are as follows:

First. rlhe gears, being inclosed in a box, are protected from ily and are kept clean and prevented from fouling or having their regulation disturbed by adhering liber.

Second. The gear and rolls moving together according to the axial reci procation of the latter, there is no wear substantially on the spindle or gudgeon of the rolls, whereas 'heretofore where the roll-spindles rotated in the hubs of the gears the wear was very great. Besides, this construction permits any of lthe rolls B to be readily taken out by simply reversing the movement of the roll for a partial revolution and then withdrawing its shafts from the hub of its gear-wheel, which may be done without disturbing any other portion of the machinery, the roll removed, if an upper one, being taken out from above, and if a lower one from beneath, whereas, with the construction heretofore adopted, when it was desired to remove a bottom roll the two rolls above it had first to be taken ont. Still further, with my construction the spindles of the rolls are all made uniform, whereas previous constructions required the upper and lower spindles to be of different lengths.

What I claim as my invention is as follows:

l. The combination, with a train of gearing for communicating motion to the rubbing-rolls of a condenser, of an in closing-box for said gearing made in two or more separable sections, substantially as and for the purpose set forth.

2. The combination, with a set of rectilinearly-reciprocating rub and drawing rolls, of gears whereby said rolls are rotated, and a box or support for said gears, with cccentrics and connections, as shown, for imparting a lateral motion to said box in unison with said rolls, whereby the latterand their gears are moved together, substantially as shown and described.

3. The combination, with the gearing-box C', having shaft-openings in its sides, of pillow-blocks E, having adjusting-brackets F, gears d', having hubs d, and rolls B, having shafts C, supported at one end in said hubs,

v substantially as shown and described.

4. The combination of the laterally-reciprocating train of gears and; a box containing the same with a shaft fixed in position except as to rotation on its axis, and a sliding joint or coupling connecting the shaft of the rst wheel of said train with said stationary shaft, substantially as shown and described.

5. The combination, with the gearing-box C', the upper rolls, B, the gearing d d, and means, substantially as described, for operating said gearing, of the adjustable pillowblocks E, and means for adjusting the same, substantially as shown and described.

6. The combination, with the rubbing-rolls of the condenser and gear-wheels connected with the shaft of said rolls, of a gear-box, an eccentric-shaft and intermediate connections, substantially as described, for imparting a reciprocating motion thereto, so as to cause said gears to move laterally with the rolls which they drive, substantially as shown and described.

7. The combination, with an upper and a lower set of rolls, of two boxes, each containing a train of gearing connected with one set of rolls, and two separate eceentrics, and intermediate connections between the same and the boxes, whereby the latter are reciprocated alternately, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of April, 1883.
